Application Prospect of Nodular Cast Iron Pipe Scaffold Fasteners
The mechanical properties,casting properties and service properties of nodular cast iron scaffold fasteners and malleable cast iron scaffold fasteners are introduced.The feasibility of using nodular iron instead of malleable iron to produce scaffold fasteners is analyzed.By comparing the mechanical properties of ductile cast iron fasteners and malleable cast iron fasteners,it is found that the mechanical properties of ductile cast iron fasteners are superior to those of malleable cast iron fasteners,such as anti-slip,anti-damage and torsional stiffness,especially the advantages of torsional stiffness are more obvious.At the same time,the production cost of ductile iron fastener is reduced by 6.8%,and energy saving and emission reduction are realized.
